Switch Mode Power Supply EPS-Series
 
 
Essen introduces the EPS series of switch mode power supply for the process control and automation needs of industry. These are rugged power supplies having over-voltage, over-current and short circuit protections. The metallic housing is rugged yet attractive and corrosion resistant.The input voltage can be switched from 110V to 230V. Output voltage is at 24V DC, 12V DC & 5V DC. Load and Line regulation are less than 1% and efficiency is also very high. The supplies are intended for high reliablity applications of industry.
Characteristics
  • Voltage and Load regulation better than 1%
  • PWM Technology
  • 150mV output voltage ripple @20MHz
  • Either universal input voltage(85-270VAC) OR switch selectable from 85-130V AC to 190-270V AC
  • Inbuilt EMI filter complying with EN55022-class B emissions.
  • Overload protection and short circuit protected
  • Robust construction using latest high reliability solid state electronic component
  • Mounting using M3 or M4 screws
  • High reliability using high temprature electrolytic capacitors
